[0001] The utility model relates to the technical field of sanitary ware, in particular to a flow-increasing pump, a flow-increasing flushing system and a toilet. Background Art

[0002] When flushing toilets currently used in buildings, a large amount of water needs to flow out instantly from the water supply source in order to supply water to the rim and bottom of the toilet bowl, so that the water from the rim can clean the toilet bowl, and the water from the bottom can siphon and flush away the dirt. However, for some buildings with low water supply pressure, there is no such strong water supply capacity. It is easy for the water supply capacity of the pipeline to fail to meet the toilet demand value during the entire flushing cycle of the toilet, resulting in an unclean flushing situation.

[0003] In order to solve the above problems, the prior art usually integrates a booster pump into the toilet tank, and allows the booster pump to work when the toilet is flushed, so as to improve the water supply capacity of the pipeline. For example, a smart flush toilet disclosed in the Chinese invention patent with announcement number CN106522337B uses a partition to separate the water tank into a washing water tank and a flushing water tank, and a first micro submersible pump is set in the washing water tank, and a second micro submersible pump is set in the flushing water tank, so as to improve the drainage flow and flushing efficiency.
